„I do not know what I may appear to the world, but to myself I seem to have been only like a boy playing on the sea-shore, and diverting myself in now and then finding a smoother pebble or a prettier shell than ordinary, whilst the great ocean of truth lay all undiscovered before me.“

— Francesco Petrarca Italian scholar and poet 1304 - 1374Context: I certainly will not reject the praise you bestow upon me for having stimulated in many instances, not only in Italy but perhaps beyond its confines also, the pursuit of studies such as ours, which have suffered neglect for so many centuries; I am, indeed, almost the oldest of those among us who are engaged in the cultivation of these subjects. But I cannot accept the conclusion you draw from this, namely, that I should give place to younger minds, and, interrupting the plan of work on which I am engaged, give others an opportunity to write something, if they will, and not seem longer to desire to reserve everything for my own pen. How radically do our opinions differ, although, at bottom, our object is the same! I seem to you to have written everything, or at least a great deal, while to myself I appear to have produced almost nothing.
